Background: A positive behavior as well as attitude of the dental students can be improvised during their undergraduate studies and thereby it is considered as an essential factor as they can further promote the oral self-care habits of their patients and hence the society in general. Objectives: The primary objective of the present study is to relate the oral health knowledge, attitude, as well as practice with the periodontal status of the undergrad¬uate dental students. Materials and Methods: The data were collected through a combination of clinical examination and self-reported questionnaire. The estimated sample size was 234. The probing depths as well as the clinical attachment loss were measured in the interproximal sites, while the gingival index was calculated on the basis of Ramfjord index teeth. Classification by the CDC and the American Academy of Periodontology was used for periodontal diagnosis. The subjects were divided into three groups. Results: The dental students participated in study were 299. Moreover, significant differences were found among the three groups in their oral health knowledge, attitude, and practice scores. The gingival disease was detected in around 99.3-99.9% and periodontitis in about 60% of the dental students irrespective of its severity. Hence a positive correlation has been established between the oral health knowledge and attitude as well as oral hygiene prac¬tice. Conclusions: Present study highlighted need in order to improve the oral health knowledge, attitude, and practice of dental students. The gingival as well as the periodontal inflammation was highly prevalent among the participants.
